[0034] In order to enable persons skilled in the art to more clearly understand the above-mentioned purposes, features and advantages of the present application, the scheme of the present application will be further described below. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application, but the present application can also be implemented in other ways different from those described herein; obviously, the embodiments in the description are only some of the embodiments of the present application, not all the embodiments.

[0036] ​​​​Some embodiments of the present application provide a cold storage box which can be applied to a cold storage device, the cold storage device can have a cold storage chamber for storing (e.g. storing medicines, vaccines, etc.) and a freezing chamber for refrigeration (or cold storage), the cold storage box can be placed in the freezing chamber to store cold when the cold storage device is working and release cold after the cold storage device is powered off, so as to maintain the refrigeration effect of medicines, vaccines, etc. in the cold storage chamber.

[0037] Referring to Figures 1 to 4 Some embodiments of the present application provide a cold storage box 1, which includes a first cold storage box body 11, a second cold storage box body 12 and a support partition 13.

[0038] The first cold storage box body 11 is formed with a first cold storage agent cavity 110, and the second cold storage box body 12 is formed with a second cold storage agent cavity 120, that is, the first cold storage box body 11 and the second cold storage box body 12 can both store cold storage agents to store cold by using the cold storage agents. The cold storage agent can be water or other cold storage substances that can store cold. Taking water as an example, the cold can be stored by changing water from liquid to solid, and when refrigeration is needed, the cold can be released by changing water from solid to liquid.

[0039] Referring to Figure 1 The first cold storage box body 11 and the second cold storage box body 12 are oppositely arranged, the support partition 13 is supported between the first cold storage box body 11 and the second cold storage box body 12, and a refrigeration air duct 14 is separated between the first cold storage box body 11 and the second cold storage box body 12, the refrigeration air duct 14 has an air duct inlet 141 and an air duct outlet 142.

[0040] That is, the cold storage box 1 adopts a combined structure, which not only can store cold storage agents for cold storage, but also has an air duct structure, so that the cold storage box 1 and the air duct are integrated, so that the air can be blown into the refrigeration air duct 14 to strengthen the convective heat transfer and improve the speed of storing and releasing cold of the cold storage box 1, thereby meeting the refrigeration demand after the cold storage device is powered off.

[0041] In addition, the cold storage box 1 adopts a combined structure, when the cold storage box 1 is applied to a cold storage device, the first cold storage box body 11 and the second cold storage box body 12 of the cold storage box 1 can be attached together and put into the cold storage device, and then the support partition 13 is supported between the first cold storage box body 11 and the second cold storage box body 12. In this way, the cold storage box 1 can be smoothly put into the cold storage device, and the support partition 13 can make the cold storage box 1 more closely attached to the wall of the cold storage device, so that the cold storage efficiency of the cold storage box 1 is higher, thereby solving the problem that the size of the integrated cold storage box is not easy to control, and the size of the cold storage box 1 is too large to cause installation inconvenience, or the size of the cold storage box 1 is too small to cause poor attachment of the cold storage box 1 to the wall of the cold storage device and affect the cold storage efficiency.

[0042] For example, the cold storage box 1 provided in this application embodiment can be applied to refrigeration equipment. The refrigeration equipment may include a freezing chamber 2, a refrigeration chamber 3 and a fan 4. The cold storage box 1 can be located in the freezing chamber 2. The freezing chamber 2 has an air inlet 221 and an air outlet 222 that communicate with the refrigeration chamber 3. The air inlet 221 is connected to the air duct inlet 141 of the refrigeration air duct 14 of the cold storage box 1, and the air outlet 222 is connected to the air duct outlet 142 of the refrigeration air duct 14 of the cold storage box 1. The fan 4 is located at the air inlet 221 or the air outlet 222. In this way, when the refrigeration equipment is powered on, the refrigerant in the cold storage box 1 can absorb the cold energy of the freezing chamber 2 for cold storage; when the refrigeration equipment loses power, a conventional micro battery can be used to power the fan 4, which blows the cold energy stored in the refrigerant in the cold storage box 1 from the freezing chamber 2 to the refrigeration chamber 3, so that the refrigeration chamber 3 can maintain the refrigeration effect for a longer period of time.

[0043] It should be noted that when the refrigeration equipment is powered normally, the cold energy stored in the refrigerant in the cold storage box 1 can also be used to blow cold energy from the freezer chamber 2 to the refrigeration chamber 3, so that the refrigeration chamber 3 can maintain a continuous refrigeration effect. With this setting, there is no need to install an evaporator in the refrigeration chamber 3, but only an evaporator in the freezer chamber 2, which simplifies the structure of the refrigeration equipment and reduces costs.

[0044] In some embodiments, refer to Figure 1 and Figure 4 As shown, there are two supporting partitions 13, which are spaced apart between the first cold storage box 11 and the second cold storage box 12. The areas on either side of the two supporting partitions 13 form air inlet duct sections 143, and the area between the two supporting partitions 13 forms air outlet duct sections 144. The air inlet duct sections 143 and the air outlet duct sections 144 are connected. This arrangement, through the separation effect of the two supporting partitions 13, divides the area between the first cold storage box 11 and the second cold storage box 12 into air inlet duct sections 143 and air outlet duct sections 144. This prevents short-circuiting of the air inlet and outlet, extends the flow length of the air within the cold storage box 1, thereby enhancing heat exchange and improving heat exchange efficiency.

[0045] For example, refer to Figure 1 and Figure 4 As shown, two supporting partitions 13 are spaced apart in the left-right direction. The left side region of the left supporting partition 13 and the right side region of the right supporting partition 13 form an air inlet duct section 143, respectively. The middle region of the left and right supporting partitions 13 forms an air outlet duct section 144. The air inlet duct section 143 and the air outlet duct section 144 are connected. The air inlet duct section 143 has an air inlet 141, and the air outlet duct section 144 has an air outlet 142. (Refer to...) Figure 4The one-way arrow in the figure shows the flow direction of the air flow. After the air flow enters the air duct inlet 141, it flows along the air inlet duct section 143 and the air outlet duct section 144 in turn, and then flows out through the air duct outlet 142. In this way, the air inlet and outlet short circuit can be prevented, the air flow length in the cold storage tank 1 is prolonged, the heat exchange is strengthened, and the heat exchange efficiency is improved.

[0046] In some embodiments, with reference to Figure 4 As shown in the figure, the two support partitions 13 are arranged to extend in the front-rear direction. The front end of each support partition 13 is flush with the front end of the first cold storage tank body 11 and the front end of the second cold storage tank 1. The length of each support partition 13 in the front-rear direction is 2 / 3 to 3 / 4 of the length of the first cold storage tank body 11 and the second cold storage tank body 12 in the front-rear direction, so as to form a communication port 145 at the rear end of each support partition 13, which communicates the air inlet duct section 143 and the air outlet duct section 144. In this way, the air inlet duct section 143 and the air outlet duct section 144 are communicated through the communication port 145, the air duct inlet 141 and the air duct outlet 142 of the refrigeration air duct 14 are formed at the front end of the cold storage tank 1, and the cold storage tank 1 is realized to take in air from the front end and take out air from the front end.

[0047] With reference to Figure 4 The one-way arrow in the figure shows the flow direction of the air flow. After the air flow enters the air duct inlet 141, it flows along the air inlet duct section 143 from front to back, changes direction through the communication port 145, flows to the air outlet duct section 144, and then flows along the air outlet duct section 144 from back to front. Finally, the air flow flows out through the air duct outlet 142, realizing the purpose of taking in air from the front end and taking out air from the front end.

[0048] It should be noted that in specific implementation, the cold storage tank 1 can be placed in the freezing chamber 2 of the refrigeration device. The freezing chamber 2 can have a front-end-opened accommodating cavity 21, and the cold storage tank 1 can be placed in the accommodating cavity 21 through the front-end opening of the freezing chamber 2. The cold storage tank 1 uses the refrigeration air duct 14 to take in air from the front end and take out air from the front end, so as to better match the structural design of the front-end opening of the freezing chamber 2, thereby more conveniently realizing the installation of the cold storage tank 1 in the freezing chamber 2.

[0049] In some embodiments, with reference to Figure 1 and Figure 2As shown, the side surface of the first cold storage box body 11 away from the second cold storage box body 12 is formed as a flat surface, and the side surface of the second cold storage box body 12 away from the first cold storage box body 11 is formed as a flat surface. In this way, when the first cold storage box body 11 and the second cold storage box body 12 are installed in the refrigeration equipment, the support partition plate 13 can be arranged between the first cold storage box body 11 and the second cold storage box body 12, and the support partition plate 13 can be used to support between the first cold storage box body 11 and the second cold storage box body 12, so that the side surface of the first cold storage box body 11 away from the second cold storage box body 12 and the side surface of the second cold storage box body 12 away from the first cold storage box body 11 can better fit the wall surface of the refrigeration equipment, thereby better ensuring the heat exchange effect of the cold storage box 1 and the refrigeration equipment, and thereby better improving the cold storage efficiency of the cold storage box 1.

[0050] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , the side surface of the first cold storage box body 11 towards the second cold storage box body 12 is formed with a plurality of first protruding ribs 111, and the side surface of the second cold storage box body 12 towards the first cold storage box body 11 is formed with a plurality of second protruding ribs 121. In this way, the heat exchange area of the side surface of the first cold storage box body 11 towards the second cold storage box body 12 and the airflow in the refrigeration air duct 14 is increased, and at the same time, the heat exchange area of the side surface of the second cold storage box body 12 towards the first cold storage box body 11 and the airflow in the refrigeration air duct 14 is increased, thereby improving the cold storage efficiency of the cold storage box 1 during operation of the refrigeration equipment, and the efficiency of the cold storage box 1 releasing cold energy after the refrigeration equipment is powered off, thereby meeting the refrigeration demand after the refrigeration equipment is powered off.

[0051] In addition, the positions corresponding to the first protruding ribs 111 in the interior of the first cold storage box body 11 can also be used to store the cold storage agent, so that the volume of the first cold storage box body 11 for storing the cold storage agent can be increased; correspondingly, the positions corresponding to the second protruding ribs 121 in the interior of the second cold storage box body 12 can also be used to store the cold storage agent, so that the volume of the second cold storage box body 12 for storing the cold storage agent can be increased.

[0052] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3As shown, the plurality of first ribs 111 are parallel and each extends in the front-rear direction, and a first groove 112 is formed between two adjacent first ribs 111. The plurality of second ribs 121 are parallel and each extends in the front-rear direction, and a second groove 122 is formed between two adjacent second ribs 121. The first ribs 111 and the second ribs 121 are opposite to each other, and the first grooves 112 and the second grooves 122 are opposite to each other. The support partition plate 13 is supported between the first grooves 112 and the second grooves 122. In this way, on the one hand, the plurality of first ribs 111 and the plurality of second ribs 121 are arranged along the flow direction of the airflow in the refrigeration air duct 14, so that the arrangement of the first ribs 111 and the second ribs 121 does not affect the flow of the airflow, ensuring the heat exchange efficiency. On the other hand, the first grooves 112 formed between two adjacent first ribs 111 are opposite to the second grooves 122 formed between two adjacent second ribs 121, and the support partition plate 13 is supported between the first grooves 112 and the second grooves 122, so as to facilitate the installation and fixation of the support partition plate 13 between the first cold accumulation box body 11 and the second cold accumulation box body 12.

[0053] In specific implementations, the support partition plate 13 can be made of a foam plate (or a foam block). The foam block has a certain deformability, so as to facilitate the installation of the support partition plate 13 between the first cold accumulation box body 11 and the second cold accumulation box body 12. Of course, the support partition plate 13 can also be made of other materials with a certain deformability. The specific size of the support partition plate 13 can be reasonably set according to the internal space of the refrigeration equipment, so that the lower surface of the first cold accumulation box body 11 and the upper surface of the second cold accumulation box body 12 can be preferably attached to the inner wall of the refrigeration equipment when the support partition plate 13 is supported between the first cold accumulation box body 11 and the second cold accumulation box body 12.

[0054] In some embodiments, as shown in Figure 1 , Figure 2 and Figure 3 , the first cold accumulation box body 11 and the second cold accumulation box body 12 are opposite to each other in the up-down direction. The first cold accumulation box body 11 is respectively formed with a first support step 113 at two opposite ends in the width direction. The second cold accumulation box body 12 is respectively formed with a second support step 123 at two opposite ends in the width direction. The first support step 113 can abut against the second support step 123.

[0055] In specific implementations, when the support partition plate 13 is not placed between the first cold accumulation box body 11 and the second cold accumulation box body 12, the second support step 123 can be matched with the first support step 113 to support the second cold accumulation box body 12 on the first cold accumulation box body 11. When the support partition plate 13 is placed between the first cold accumulation box body 11 and the second cold accumulation box body 12, if the height of the support partition plate 13 is relatively high, a certain gap will be formed between the second support step 123 and the first support step 113.

[0056] It should be noted that the upper surface of the first support step 113 can be arranged higher than the upper surface of the first convex rib 111, and the lower surface of the second support step 123 can be arranged lower than the lower surface of the second convex rib 121. In this way, when the second support step 123 is in abutting cooperation with the first support step 113, a gap is formed between the second convex rib 121 and the first convex rib 111, so as to ensure that the air flow can pass through the gap between the first convex rib 111 and the second convex rib 121.

[0057] In some embodiments, referring to Figure 1 and Figure 2 It is shown that the first cold storage tank 11 and the second cold storage tank 12 have the same structure. That is, the first cold storage tank 11 can have the same structure as the second cold storage tank 12. In this way, one set of molds can be used to manufacture the first cold storage tank 11 and the second cold storage tank 12, and the processing and manufacturing are more convenient. During assembly, one of the cold storage tanks 1 is flipped over and placed above the other cold storage tank 1, and a support partition 13 is arranged between the two cold storage tanks 1, thereby forming a cold storage tank 1.

[0058] Referring to Figure 5 and Figure 6 It is shown that some embodiments of the present application provide a refrigeration device, which includes a freezing chamber 2, a refrigeration chamber 3, a fan 4, and a cold storage tank 1 according to any of the above embodiments. The cold storage tank 1 is arranged in the freezing chamber 2. The freezing chamber 2 has an air inlet 221 and an air outlet 222 which are in communication with the refrigeration chamber 3. The air inlet 221 is in communication with the air inlet 141 of the refrigeration air duct 14, and the air outlet 222 is in communication with the air outlet 142 of the refrigeration air duct 14. The fan 4 is arranged at the air inlet 221 or the air outlet 222.

[0059] The refrigeration device provided by the embodiments of the present application has the following advantages. By arranging the cold storage tank 1 in the freezing chamber 2, when the refrigeration device is powered on, the cold storage agent in the cold storage tank 1 can absorb the cold energy of the freezing chamber 2 for storage. When the refrigeration device is powered off, the fan 4 can be powered by a conventional micro battery, and the cold energy stored in the cold storage tank 1 can be blown from the freezing chamber 2 to the refrigeration chamber 3, so that the refrigeration chamber 3 can maintain a longer refrigeration effect.

[0060] In order to ensure that the refrigeration device can maintain the refrigeration effect after being powered off, a battery or other power storage component can be arranged on the refrigeration device. When the refrigeration device is powered on, the battery is charged to a full state. The power storage component is electrically connected to the fan 4. In this way, when the refrigeration device is powered off, the battery can be used to power the fan 4, and the fan 4 can blow the cold energy stored in the cold storage tank 1 from the freezing chamber 2 to the refrigeration chamber 3, thereby maintaining the refrigeration effect of the refrigeration chamber 3 for storing medicines and vaccines.

[0061] It should be noted that when the refrigeration device is normally powered, the cold energy stored in the cold storage agent in the cold storage tank 1 can also be used to blow from the freezing chamber 2 to the refrigeration chamber 3, so that the refrigeration chamber 3 can continuously maintain the refrigeration effect. In this way, the evaporator can be arranged only in the freezing chamber 2 without being arranged in the refrigeration chamber 3, so that the structure of the refrigeration device is more simplified and the cost is lower.

[0062] In some embodiments, referring to FIGS. 1, 2 and 3, the refrigeration device comprises a freezing chamber 2, a refrigeration chamber 3, a cold storage tank 1, a fan 4 and an evaporator 5. Figure 5 Figure 6 As shown in FIGS. 1, 2 and 3, the freezing chamber 2 has a receiving cavity 21 with an open front end, the cold storage tank 1 is arranged in the receiving cavity 21, and a door cover 22 is arranged at the open front end of the receiving cavity 21. The front end of the cold storage tank 1 is formed with an air duct inlet 141 and an air duct outlet 142, the door cover 22 is formed with an air inlet 221 corresponding to the air duct inlet 141 and an air outlet 222 corresponding to the air duct outlet 142, and the fan 4 is arranged at the air outlet 222.

[0063] In this way, the freezing chamber 2 and the refrigeration chamber 3 are separated by the door cover 22, the freezing chamber 2 and the refrigeration chamber 3 are communicated by the air inlet 221 and the air outlet 222 arranged on the door cover 22, and the fan 4 is arranged at the air outlet 222, so that under the action of the suction force of the fan 4, the air in the refrigeration chamber 3 can enter the refrigeration air duct 14 of the cold storage tank 1 through the air inlet 221 on the door cover 22, and the refrigeration gas in the cold storage tank 1 is heated and blown to the refrigeration chamber 3 through the air outlet 222 on the door cover 22, so as to maintain the refrigeration effect of the medicines and vaccines in the refrigeration chamber 3.

[0064] Of course, in specific implementation, the fan 4 is not limited to being arranged at the air outlet 222, but can also be arranged at the air inlet 221 according to needs, and the specific arrangement position of the fan 4 can be reasonably arranged according to actual conditions.

[0065] In addition, it should be noted that in the normal power supply mode, the refrigeration device can be powered by mains power supply or solar power supply, and the power supply mode is not limited here.
